Fueled by Fear

I had another image within my head and I wanted to get it out again and guess what - it doesn't look like it whatsoever. Oh dear... the original idea was to have a diseased equine entering a city (yeah I know, pretty horrible) to bring it to it's final destruction and look at this - nothing like it! Well you can make your own story for this one, the horses look like the ones being destroyed here. [Edited: Got some friends to have a look at it and they passed on great suggestions, thanks]
